Description
Technical field
The utility model relates to quartz watch technical field, particularly relates to a kind of quartz watch movement stepper motor and to be locked structure.
Background technology
Existing volume production fossil English timepiece movement generally adopts PC plastic casing-pipe locking as shown in Figure 1, but a large amount of production and this technical scheme of Market reaction deposit a large problem: because of sleeve pipe wringing fit always, deposit large drawing stress, cause plastic casing-pipe to ftracture to get loose, step motor stator sheet and iron-core coil is caused to get loose, output torque reduces, and motor performance declines, and draws movement and stops slow table.And this problem not timing occurs, assemble finished product wrist-watch all likely occur from producing to, this has become affects movement quality one hidden danger greatly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and not easily loosens the reliably structure and quartz watch movement stepper motor not easy to crack is locked.
The technical solution adopted in the utility model is:
A kind of quartz watch movement stepper motor is locked structure, it comprises disc spring, bottom plate and stepper motor, described stepper motor comprises the iron-core coil and stator piece that are wound with coil, described bottom plate is provided with reference column, described disc spring, iron-core coil and stator piece are sheathed on reference column from top to bottom successively, described reference column is more than two, described disc spring comprises annular disc spring body, the inside edge of disc spring body is evenly provided with more than three acclivitous spines, spine upper end is thrust reference column and is arranged, the lower surface of disc spring body is along the circumferential direction evenly provided with more than three downward-sloping shell fragments, the upper surface that described shell fragment is close to iron-core coil is arranged.
Described disc spring is shaping through punch process by high-carbon steel material, and heat treatment hardness reaches HV600-700.
Described bottom plate and reference column are by PC plastic material integrated injection molding.
Described spine is triangle.
The utility model adopts above technical scheme, bottom plate by PC plastic material single injection-molded there is the reference column of more than two, bottom plate is successively after assembling stator sheet, iron-core coil, sheathed upper high rigidity high resiliency disc spring, disc spring body and reference column interference fit, the unidirectional triangle spine of disc spring inserts in plastic material reference column simultaneously, plays unidirectional locking effect, only with downwards, can not upwards fall back.The lower surface of disc spring is provided with shell fragment, can play and remain that iron-core coil and stator unilateral 3 fit tightly effect.The utility model adopts the stamping forming disc spring of high-carbon steel to get for plastic casing-pipe structure, and metal material is made a concerted effort at close-fitting, there is not cracking phenomena, can lock stator piece and iron-core coil all the time, can not cause the phenomenon that gets loose, and improves movement qualification rate and dependability.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details;
The structural representation of the PC plastic casing-pipe that the existing quartz watch movement of Fig. 1 adopts;
A kind of quartz watch movement stepper motor of Fig. 2 the utility model is locked the structural representation of structure;
A kind of quartz watch movement stepper motor of Fig. 3 the utility model is locked the vertical view of disc spring of structure
A kind of quartz watch movement stepper motor of Fig. 4 the utility model is locked the cut-open view of disc spring of structure.
Embodiment
As shown in one of figures 2-4, the utility model it comprise bottom plate 5, stepper motor and disc spring 1, described stepper motor comprises the iron-core coil 6 and stator piece 3 that are wound with coil 4, described bottom plate 5 is provided with reference column 2, described disc spring 1, iron-core coil 6 and stator piece 3 are sheathed on reference column 2 from top to bottom successively, described reference column 2 is more than two, described disc spring 1 comprises annular disc spring body 10, the inside edge of disc spring body 10 is evenly provided with more than three acclivitous spines 11, spine 11 upper end is thrust reference column 2 and is arranged, the lower surface of disc spring body 10 is along the circumferential direction evenly provided with more than three downward-sloping shell fragments 12, the upper surface that described shell fragment 12 is close to iron-core coil 6 is arranged.
Described disc spring 1 is by high-carbon steel material through impact briquetting, and heat treatment hardness reaches HV600-700, makes this disc spring have high high rigidity and elastomeric feature.
Described bottom plate 5 and reference column 2 are by PC plastic material integrated injection molding.
Described spine 11 is triangle.
The principle of work of the present embodiment 1: the reference column 2 bottom plate 5 by PC plastic material single injection-molded having more than two, bottom plate 5 is successively after assembling stator sheet 3, iron-core coil 6, sheathed upper high rigidity high resiliency disc spring 1, disc spring body 10 and reference column 2 interference fit, the unidirectional triangle spine 11 of disc spring 1 inserts in plastic material reference column 2 simultaneously, play unidirectional locking effect, only with downwards, can not upwards fall back.The lower surface of disc spring 1 is provided with shell fragment 12, can play and remain that iron-core coil 6 and stator unilateral 3 fit tightly effect.This latch mechanism can make stator piece 3 and iron-core coil 6 fit tightly, and form magnetic loop, and magnetic resistance is minimum, efficient magnetic conduction, improves movement quality and dependability.
